Final answer:
A schizophrenic with alternating periods of mute immobility and excited motor activity is a catatonic schizophrenic. They may experience phases of being motionless or mute, as well as hyperactivity. Treatment typically involves antipsychotic medications, which are effective but not a cure.
Step-by-step explanation:
A schizophrenic characterized by alternating periods of mute immobility and excited motor activity is referred to as a catatonic schizophrenic. This form of schizophrenia is characterized by periods where patients may be virtually immobile or mute, followed by intervals of extreme hyperactivity. In some instances, the patient may hold rigid poses for hours, refuse to speak or move (catatonic stupor), or may move all over the place without any purpose (catatonic excitement).
Treatment for schizophrenia usually involves antipsychotic medications that work by blocking dopamine receptors, which helps to alleviate the symptoms. Despite medications being quite effective at treating schizophrenia, they do not provide a cure and are required to be taken on a long-term basis.
